METHOD OF TRANSMITTING AND RECEIVING CONTROL INFORMATION IN A WIRELESS COMMUNICATION SYSTEM

摘要

A method of transmitting and receiving control information in a wireless communication system is disclosed. The method of receiving control information related to a specific point-to-multipoint service in a user equipment of a wireless communication system comprises receiving a notification message including indication information and an identifier identifying the point-to-multipoint service from a network, the indication information indicating at least one downlink channel related to the specific point-to-multipoint service among a plurality of downlink channels established for transmission of control information for at least one or more point-to-multipoint service, and receiving at least one downlink channel indicated by the indication information.

1. A method of receiving a signal associated with a broadcast or multicast service, the method comprising:
receiving, by a device, a signal carrying a plurality of OFDM (Orthogonal Frequency Division Multiplexing) symbols in a time domain and a plurality of subcarriers in a frequency domain, wherein the plurality of OFDM (Orthogonal Frequency Division Multiplexing) symbols carry a frame including subframes, wherein a part of continuous OFDM symbols in the subframes is used for transmission of physical signal channel and a remaining part of continuous OFDM symbols in the subframes is used for transmission of a data channel in physical layer, wherein the subframes include Layer 1 (L1) information channel and Layer 2 (L2) information channel which are located at beginning parts of the subframes, and wherein the Layer 1 (L1) information channel includes identification information for uniquely identifying a data channel carrying the associated broadcast or multicast service, and allocation information on position of the associated broadcast or multicast service in a subframe, wherein the allocation information indicates address information of the data channel in a time or frequency-region.
